To all whom t may concern:

'Bye it known that L VYILLrAM CnAMnR, a citizen of the United States of America, anda `'resident of the city of St. Lou-s and State of Missouri, have invented Acertain nevv and useful 'improvements in Belt..- lia'stening Devices, of vvhichthe following is a full," clear, and eXact description, rel".- erence being had to the accompanying drawings, -orniing a part of this specilication Mh'lfhifs' invention relates to improvements in "belt Jfastening devices and particularly `to a device for applying metallic belt ilacings to power transmitting belts. rilhe device disclosed `heiiein is yespecially in# tended and'adapted for use in connection with a Well knovvn and standard form oi" staples used-for belt lacingsf and the invention relates particularly to the Ameans for fielding these staples While they are being securedto the'ends of the belt.

-The object ofthe invention is to produce a simple and inexpensive device which will be eiiicient in use and which is of such durable construction as to be able to Withstandtlie rough usage to which devices of this hind are subjected.

With the foregoing and other, objects in view, the invention comprises the novel V.construction, .combination and arrangement of parts hereinafter Vmore specifically de,- scribed and illustrated in the accompanying drawings wherein is shown the prefer-red embodiment of the invention. l'lowevenit is to be understood that the invention oomprehends changes, variations and modiiications which vcome Within thescope of the claims vhereunto appended.

ln' the drawings', ii dsglet my i111* proved belt fastening devise' which .Ceinprises an" anvil B, staple'lwdirlg mtlhailill l() and a hammer Di The anvil LB ispreferably formed of .comparatvelyheavv metal and is provided `ivitha plurality of reinforcing ribs B I.which er@ iltlfled f3.0 add .durability to said anvil, and .iS flSO provided with a head portion E at tS per end. i i

Mounted `on the -anvil l immediately an enlarged fragmentary view above the head pontion is the staple liolding mechanism C, said mechanism comprislng a base 'plate l, an intermediate `.plate -2 and a top-plate 3. platesl, 2 .and 3 extend practically the fnll, Width of rthe Aanvil and the plates l and are provided vvith simple .teeth .4 which are" preferably formed by ,cutting a plurality Oli' Slots along one ofthe edges of eachof said plates. The intermediate plate 2 is provided with teeth 5, each of said teeth being Apenovided with .alaterally7 projecting portion .6 at its louter end. The ilates '1,' 2 and 3 .aresecuredto the anvil by means .of a lpair ,ofi rivets 7 which .pass through said plates and. through the head portion .of the' anvil rlihe openings in the Lplate's l yand 3 tlirpugh which the rivets 7 pti-ss are ot the approxie mate diameter of said rivets Wsllenebysaid .plates l and .3 will be firmly -iiixedgto said anvil, but ,the rivet openings 8 in the in- .termediate plate -2 are ott milch greater .diameter than said rivets, hence said ilfltel1- mediate plate 2 is capable ,of moving `relative to A.the pla-tes l and 3. The plate l is provided with an upstand-ing lug :9 ad jacent to eachoi its ends and 4the lintermedi-ate plate 2 is provided ".vvith'a :pair of slots l0 Which are adapted to Vreceive said "lugs when the plates are assembled. The

'I faces, on the lshort kbar 12. The short bar I i. slots are of fleflte'v length than the lugs 9 (Egf I), hence-.becauseof the enlarged openings 8 and elongated slots 10 in the vplate 2, said plate maybe moved longitudinally ofthe plates 1 and l3.

Extending upwardlyfrom the' intermediate plate 2 is a pin 11fon which aqshort ybar 12,is pivotally mounted,said bar be-v ing provided with eccentric faces 13 at its ends. The upper plate 3 is provided with .acutoutportion 14.*an`d fthe bar 12 is parftiallyr located f withinv- .this cutout portion.

e The cutout portion 14 ofathe 'bar 3 is prothe pin 11 by means "Assuming that Vitis desired to place a plurality of staples' S in the staple :holder vC'. l. Theintermediate plate v2 isbrought to theposition in whichit is shown in Fig. X `of the'drawing-wherein the projections 6 on the teeth on'said plate are drawn out of Kline withl the slots in the plates :land V3.

' With'zthe parts in the position described the staplesmaybe inserted inthe slots as shown in *Fig II. l,Itis now desired to movevk the projections (Sinto-the' slots soas to' lock the staples insa-id slotsv and this may be' accom- '.jl'plshed by depressing onev end of the bar 1.2'thus moving the eccentric face 131km the-barf12 against-the associated cam' face 15 infthe ycutout portion 14., The top'plate y3isvlheldj.stationary by the rivets 7 and as the distance yfrom the centerof the pin 1v1 to theouter corner of the face 13a is greater than the distance. from the'center of said pin' tothe inner corner of face 13a, the effect 'ofthe' movement of the face 13a against the ';k thecurved portionsof the staples S wherebyy saidl staples are locked in place within the face 15' will be to cam the intermediate plate 2 longitudinally of they plates land A 3,1thus moving the projections in front -of y. slots.4 "Whenlit' is :desired to lwithdraw the staples from* the slots, ythe. eccentric face 1'3" is' moved .against the associated cam face i j 15 in the cutout portion 14v oftheplate 3,

. whereby theplate 2 is moved in a direction y 1 J designates a knife. which is pivoted to ,j the anvil at thel point indicated bythe refy' erence character K. f

mi 'to'withdraw said projections@ from said slots,thusreleasing the staples S. y The'fhammerl D of my improved kbelt vfastening device comprises a head yportion F and a pairv of arms G, said hammer being pivoted tothe head portion'E of thepanvil Ajby vmeans offaf'pair of pins I-I.

1 Before.' stapling the V:end of av piece of belting it is necessary to make a clean cut across said end so that it will fit truly into the tool and receive the staples in a straight vline and this is accomplished by insertin the end.of said belting under the pivote knife J and driving said knife downwardly. The staples are' placed in the staple holder C asalready described and as shown in Fig. II, and the end of the belt is passed between the upperand lower points of the staples. The hammer D is then brought to the position shown by` dotted lines in Fig. I in which position said hammer is struck a hammer blow Awhereby the staples are driven into thebelting as shown in Fig.- XIII.

The belt ends are secured ,together by overlapping-the staples S on the belt ends as shown in FigfIX and then inserting a rod R through said overlappedstaples.
